Yes, it is a “dream” way in the sense of: We are not there yet. Not even close wrt Plex.
It is not a “dream”, though, in the sense, that this is unachievable. The technology is already there and continues to mature: The goal is continually becoming easier to achieve and with better results.
Yes, for now succumbing to “the Plex way” and doing “the Plex dance” and other things makes life a lot easier.
The point is, that for many people figuring out the Plex way is not easy: The forum is loaded with requests on library management.
So aside from the philosophical question, how much humans should succumb to technology vs. the other way round, there is a very practical aspect, that all in all the current system works ok at best. It takes time and energy of ordinary users and helpful forum contributors. Time and energy that should better be used to e. g. enjoy a film or take a walk outside.
Content-based file matching might be a “dream” now. That does not mean, that it isn’t the right direction to go forward.
Imagine a Plex, where you can just dump stuff into a staging folder, then automagically Plex creates a well sorted library (based on your preferences for how things should be sorted).
